Problem
◦
Lack of standardisation mechanisms, that
enable state
-
of
-
the
-
art
of medical educational resources
to be discovered, retrieved,
shared and re
-
used across European Academic Institutions
MedBiquitous Annual Conference 2011
Solution
◦
Standardised format of description of the resources by means of metadata
◦
Metadata need to be described by state
-
of
-
the
-
art e
-
learning standards
and make use of their many advantages
Semantic Web, Linked Data
Aim
◦
To improve medical & healthcare education

General Characteristics

Need to be widely used (interoperable)
Reusing existing e

learning standards
Should not reinvent the wheel
Extending e

learning standards to describe new concepts
i.e. Repurposing, Companionship, Attention

Standardisation format in order to enable
sharing and retrieving of resources is essential
Choice of the right format (RDF/XML) will link
the data of the Web. Benefits:
◦
Access existing knowledge
◦
Interoperability between resources
Shift towards an Ontology

Aim:
To enable specialized state

art medical
educational content of varying types to be
discovered, retrieved, shared and re
-
used across
European higher academic institutions.
How:
By implementing and evaluating two different
solutions
•
A “mashup” platform that aggregates content published in
isolated Learning Content Management Systems (LCMS)
•
A federated architecture of LCMSs based on Semantic Web
Services for search, interchange and delivery of learning objects
